Check for data lake querying, materialized views, query concurrency, and real-time ingestion, along with whether compute and storage are separate. Deployment model, free plan availability, and starting prices round out the listed comparison points. Exasol and CrateDB appear first, with Apache Druid also among the leading entries.
